geared towards the prevention of accidents, industrial
diseases, labor-related health risks are taken and mea-
sures towards making the workplace fit for people to
work in are carried out.
Specifications for electrical systems (BGV A3)
Electrical engineering in Germany is subject to the ac-
cident prevention regulations of the trade association
"Electrical Plant and Equipment as under BGV A3 (previ-
ously VBG 4)". In all other countries, the applicable nati-
onal regulations acts or decrees are to be adhered to.
Basic rules
The contractor is bound to ensure that all electrical
equipment and operating material is set up, modified

3. Safety instructions
3.1 Risk of electric shocks
3.1.1 Low voltages, high voltages
Hazardous voltages occur in both the lighting
system and the electrical system of a motor
vehicle. If contact is made with live parts
(e.g. with the ignition coil), there is a risk of
electric shock from flashover voltages caused
by damaged insulation (e.g. ignition cables
which have been attacked by martens). These
apply to the secondary and primary sides of
the ignition system, the wiring harness with
connectors, lighting system (Litronic) as well
as connection to the vehicle.
Safety measures:
Only connect to a properly grounded outlet.
Only the enclosed or a tested power supply cable is
to be used.
All extension cables must be fitted with shock-proof
contacts.
Any cables with damaged insulation must be repla-
ced.
First connect the lighting system and turn it on befo-
re connecting it to the vehicle.
Before switching on the ignition connect the (B-)
cable to engine ground or the battery (B–) terminal.
Always switch off the ignition before performing any
work on the electrical system of the vehicle. Inter-
vention includes, for instance, connection to the
vehicle, replacement of ignition system components,
removal of equipment (e. g. alternators), connection
of equipment to a test bench.
Wherever possible, tests and settings should always
be caried out with the ignition switched off and the
engine stationary.
If tests or settings are carried out with the ignition
switched on or the engine running, care must be
taken not to touch any live parts. This applies to all
connection cables and leads as well as to connec-
tions of equipment to test benches.
Test connections must always be made using sui-
table connectors (e.g. Bosch testing cable set or
vehicle-specific adapter cables).
Make sure that all test connections are properly
plugged in and secure.
Before disconnecting the (B-) cable from the engine
ground or battery (B–), switch off the ignition.
Never open the enclosures.
3.1.2 High voltages in hybrid vehicles and electric ve-
hicles as well as their high-voltage components
If high-voltage components or high-voltage
wires are inexpertly handled, there is a risk of
fatal injury from high voltages and the possib-
le transmission of current through the body.
Deenergization is only to be performed by
a qualified electrician, a qualified electri-
cian for specific tasks (hybrid) or a power
systems engineer.
Work on vehicles with high-voltage compo-
nents is only ever to be performed in a safe,
deenergized condition by persons with the
minimum qualification "Trained to perform
electrical work".
Even after deactivating the high-voltage
vehicle electrical system, the high-voltage
battery may still be live.
Operating condition cannot be established
from any running noise, as the electric ma-
chine is silent when stationary.
In gear positions "P" and "N" the engine or
electric motor may start spontaneously depen-
ding on the charge of the high-voltage battery.
Safety measures:
Never open or damage high-voltage batteries.
On accident vehicles, never touch high-voltage com-
ponents or exposed high-voltage wires before deacti-
vating the high-voltage vehicle electrical system.
Avoid contact with any high-voltage components
and high-voltage wires (orange sheathing) when in
operation.
Secure against unauthorized renewed start-up
(e.g. by means of a padlock).
Always wait at least 10 seconds after deactivating
the high-voltage system.
Visually inspect the high-voltage components and
high-voltage wires for damage. The power systems
engineer responsible should always be immediate-
ly notified of any irregularities, doubts or defects
found.
$High-voltage components must never exhibit signs
of external damage.
$The insulation of the high-voltage wiring must be
intact and undamaged.
$Watch out for any abnormal deformation of the
high-voltage wiring.

3.2 Danger of acid burning
When exhaust gas measurements are taken,
the sampling hoses which are used release a
highly caustic gas (hydrogen fluoride) that can
cause acid burning in the respiratory system
when heated to temperatures in excess of
250 °C (482 °F) or in the event of fire.
Rules of conduct:
Consult a doctor immediately after inhaling!
Always wear gloves made of neoprene or PVC when
removing residues left after a fire.
Neutralize any residues left after a fire with a cal-
cium hydroxide solution. This produces non-toxic
calcium fluoride, which can be washed away.
Acids and alkalis can cause severe burning on
unprotected skin. Hydrogen fluoride in combi-
nation with moisture (water) forms hydroflu-
oric acid. The condensate, which accumulates
in the sampling hose and in the condensate
container likewise contains acid.
Rules of conduct:
When replacing the O2 measuring sensor, bear in
mind that it contains alkali.
When replacing the NO measuring sensor, bear in
mind that it contains acid.
Rinse any affected parts of the skin immediately in
water, then consult a doctor!
NO and O2 measuring sensors are hazardous waste
and must be disposed of separately. Your Bosch spe-
cialist equipper can dispose of sensors in the proper
manner.
If liquid crystal escapes from a damaged liquid
crystal display, it is imperative to avoid direct
skin contact, inhalation and swallowing.
Rules of conduct:
If you have inhaled or swallowed liquid crystal, con-
sult a doctor immediately!
Wash the skin and clothing thoroughly with soap and
water if it has come into contact with liquid crystal.
If fluid (electrolyte) escapes from batteries
and rechargeable batteries, avoid getting it on
your skin or in your eyes.
Rules of conduct:
If contact with skin or eyes happens nevertheless,
wash the affected parts immediately with clean wa-
ter and then consult a doctor.
3.3 Danger of injury, Danger of crushing
The vehicle has rotating and moving parts
that can injure fingers and arms.
If the vehicle is not prevented from rolling
away, there is a danger of people being crus-
hed against a workbench, for example.
There is the risk with electrically operated
fans in particular that the fan can start run-
ning unexpectedly even when the engine and
ignition are off.
Safety measures:
Take steps to prevent the vehicle from rolling away
while it is being tested. Select the park position if the
vehicle has an automatic transmission and apply the
handbrake or lock the wheels with chocks (wedges).
Operating staff must wear work clothes without
loose bands and loops.
Do not reach in any area with rotating or moving parts.
When working on or in the vicinity of electrically
driven fans, allow the engine to cool down first, then
disconnect the plug of the fan motor.
Route cables at a suitable distance from rotating parts.
Secure the trolley against rolling away by setting the
brakes.
Do not place heavy objects on or lean on the sensor
holder.
Transport and operate the equipment only in ac-
cordance with the operating instructions.

22 | KT700 VMI | Safety instructionsen
3.4 Danger of burning
When working on a hot engine, there is a risk
of injury from burning if such components as
the exhaust gas manifold, the turbo-charger,
the Lambda sensor, etc. are touched or if
parts of the body come too close to them.
These components may be heated to tempe-
ratures of several hundred degrees Celsius.
Depending on the duration of the exhaust
gas measurements, the sampling probe of the
exhaust gas measuring instrument may also
become extremely hot.
Safety measures:
Always wear protective clothing, e.g. gloves.
Allow the engine to cool down first. This also applies
to auxiliary heating systems.
Keep connecting cables well away from all hot parts.
Do not leave the engine running any longer than
necessary for the test or setting.
3.5 Danger of fire, Danger of explosion
There is a risk of fire and explosion from fuels
and fuel vapors when work is performed on
the fuel system or on the mixture control
system.
Safety measures:
Switch off the ignition.
Allow the engine to cool down first.
Avoid naked flames and potential sources of sparks.
Do not smoke.
Collect any leaked fuel.
Always ensure effective ventilation and suction when
working in closed areas.
3.6 Danger of asphyxiation
Car exhaust fumes contain carbon monoxide
(CO) - a colorless, odorless gas. If inhaled,
carbon monoxide causes an oxygen deficien-
cy in the body. Extreme caution is therefore
essential when working in a pit, as some of
the components of the exhaust gas are heavier
than air and settle at the bottom of the pit.
Caution is also necessary when working on
LPG-driven vehicles.
Safety measures:
Always ensure effective ventilation and suction (es-
pecially when working in a pit).
Always switch on and connect the suction plant in a
closed area.
3.7 Danger of tripping
When conducting tests or making adjust-
ments, the sensor and connection cables
increase the risk of tripping.
Safety measures:
Route the connecting cables such that any risk of
tripping up is prevented.
3.8 Noise
Noise levels in excess of 70 dB(A) can oc-
cur when measurements are carried out on
a vehicle, especially at high engine speeds.
Damage to hearing may result if human beings
are exposed to noise at such levels over an
extended period of time.
Safety measures:
Noise protection facilities must be provided by the ow-
ner at all workplaces in the vicinity of the testing area.
Suitable personal noise protection facilities must be
used by the operator.

iTrigger function can only be used at high frequenci-
es.
10.3.3.1 Trigger position
Trigger position determines the length of viewable si-
gnal both preceding and following a grigger point. Va-
rying the trigger position allows you to capture what a
signal did before a trigger event.
You can set the trigger position through directly drag
the slider at the top of waveform drawing area.
10.3.3.2 Trigger channel
Use the trigger level to stabilize a repeating signal, or
to trigger on a single event. Trigger channel only be
selected by opened channels, and only used when the
frequency is less than 100ms/div.

The trigger level provide the basic trigger point defini-
tion, when inputed amplitude more than trigger level,
VMI will trigger.
You can set the grigger level through directly drag
the arrowhead on the right of waveform drawing
area.
10.3.3.4 Trigger type
There have 4 trigger type, as follow:
Level trigger: VMI will be user-set trigger level position
as a basic trigger point, when the rising edge amplitude
of the input waveform greater than the trigger level, VMI
will trigger waveform.
Rising edge of the trigger: VMI will trigger on the rising
edge of the input waveform.
Falling edge of the trigger: VMI will trigger on the falling
edge of the input waveform.
Automatic level trigger: VMI will automatically calculate
the trigger position, and trigger at position of the rising
edge greater than trigger level, and simultaneously up-
date trigger level position of VMI software.
8.3.4 Negate routine
Select the channel, the waveform will reverse display
based on waveform position. Default is off, check was
opened.
8.3.5 Adjust cursor
The cursor is to be measure the voltage amplitude and
period. Cursor measurement parameters to the current
channel as a reference.
Click the cursor with time and voltage, according to the
time(abscissa) move, according to the voltage(vertical
axis) move, and display the measurements between
cursors.

8.4 Sensor Measure
8.4.1 Manifold Absolute Pressure Sensor (MAP)
Manifold absolute pressure sensor provides engine con-
trol unit (ECU) with engine load signal, which generally
is frequency-modulated square wave signal or voltage
level signal (depending on manufacturer) and is used to
change mixing ratio of fuel and other output value after
being processed by ECU.
When engine load increases, manifold pressure increa-
ses, or manifold pressure is low. Damaged MAP sensor
may affect air-fuel ratio when engine accelerates or
decelerates, and may affect ignition timing and other
computer output values.
Connecting Equipment
When connecting VMI to power extension cable for
power supply, choose power supply according to the
battery position of vehicle mode tested. All connec-
ting diagrams in this users manual take power supply
by battery clip power cable as example. Oscilloscope
probe(Main line) connect to Channel 1 (CH1 port), and
then put black alligator clip or black pierce probe in
oscilloscope probe(Secondary line) connect to the ne-
gative of battery or grounding, Put red pierce probe in
oscilloscope probe(Main line) into the trigger signal line
of manifold absolute pressure sensor (MAP).

Measure conditions
RSwitch on automobile ignition switch, do not start
engine. Use manual vacuum pump to simulate vacu-
um and connect it to vacuum input port of manifold
absolute pressure sensor.
RMonitor signal from idle to acceleration with engine
running.
Measure steps
1. Connect equipment according to Fig 6, switch on
power supply;
2. Double click run KT700 software;
3. Communication connect ;
4. Click Auto analyzer
Sensor measure
MAP;
5. Waveform will be displayed on the screen depending
on measure conditions;
6. You can adjust X-deflection, amplitude, coupling,
negate routine, and cursor. If X-deflection at high
frequencies, you can also adjust the triger channel
and trigger mode;
7. You can also print measure data, loading waveform,
save or read config, automatic adjust amplitude,
freeze waveform, freeze setting, capture and wave-
form comparison;
8. If you want to read waveform on current display, you
can click "Pause" button,
9. You can click "Record" button to record a continuous
waveform.
Waveform Analysis
Generally, analog quantity output is common except
that the output of manifold absolute pressure sensor
in FORD is digital signal. Manifold pressure sensor of
analog quantity produces a voltage to ground signal
of about 0V in high degree of vacuum, and produces a
high voltage to ground signal in low degree of vacuum
(approaching atmospheric pressure). Refer to repair
manual since different manufacturers may have diffe-
rent indexes.
Digital MAP sensors are mounted on many FORD and
LINCOLN vehicles. Output waveform in digital quantity
should be pulse with amplitude value of 5V, at the same
time, shape is correct, waveform is steady, square angle
of rectangle is correct and rising edge is vertical. Fre-
quency and its corresponding degree of vacuum shall
comply with the values given in repair materials.
